Constructor & Destructor Documentation

ns3::ndn::AppDelayTracer::AppDelayTracer ( shared_ptr< std::ostream >  os,
Ptr< Node >  node 
)

Trace constructor that attaches to all applications on the node using node's pointer.

Parameters
osreference to the output stream
nodepointer to the node

Definition at line 174 of file ndn-app-delay-tracer.cpp.

ns3::ndn::AppDelayTracer::AppDelayTracer ( shared_ptr< std::ostream >  os,
const std::string &  node 
)

Trace constructor that attaches to all applications on the node using node's name.

Parameters
osreference to the output stream
nodeNamename of the node registered using Names::Add

Definition at line 188 of file ndn-app-delay-tracer.cpp.

ns3::ndn::AppDelayTracer::~AppDelayTracer ( )

Destructor.

Member Function Documentation

void ns3::ndn::AppDelayTracer::Destroy ( )
static

Explicit request to remove all statically created tracers.

This method can be helpful if simulation scenario contains several independent run, or if it is desired to do a postprocessing of the resulting data

Definition at line 46 of file ndn-app-delay-tracer.cpp.

References ns3::ndn::g_tracers.

void ns3::ndn::AppDelayTracer::Install ( const NodeContainer &  nodes,
const std::string &  file 
)
static

Helper method to install tracers on the selected simulation nodes.

Parameters
nodesNodes on which to install tracer
fileFile to which traces will be written. If filename is -, then std::out is used
Returns
a tuple of reference to output stream and list of tracers. !!! Attention !!! This tuple needs to be preserved for the lifetime of simulation, otherwise SEGFAULTs are inevitable

Definition at line 89 of file ndn-app-delay-tracer.cpp.

References ns3::ndn::g_tracers.

Referenced by Install(), and InstallAll().

void ns3::ndn::AppDelayTracer::Install ( Ptr< Node >  node,
const std::string &  file 
)
static

Helper method to install tracers on a specific simulation node.

Parameters
nodesNodes on which to install tracer
fileFile to which traces will be written. If filename is -, then std::out is used
averagingPeriodHow often data will be written into the trace file (default, every half second)
Returns
a tuple of reference to output stream and list of tracers. !!! Attention !!! This tuple needs to be preserved for the lifetime of simulation, otherwise SEGFAULTs are inevitable

References ns3::ndn::g_tracers, and Install().

Ptr< AppDelayTracer > ns3::ndn::AppDelayTracer::Install ( Ptr< Node >  node,
shared_ptr< std::ostream >  outputStream 
)
static

Helper method to install tracers on a specific simulation node.

Parameters
nodesNodes on which to install tracer
outputStreamSmart pointer to a stream
averagingPeriodHow often data will be written into the trace file (default, every half second)
Returns
a tuple of reference to output stream and list of tracers. !!! Attention !!! This tuple needs to be preserved for the lifetime of simulation, otherwise SEGFAULTs are inevitable

void ns3::ndn::AppDelayTracer::InstallAll ( const std::string &  file)
static

Helper method to install tracers on all simulation nodes.

Parameters

void ns3::ndn::AppDelayTracer::PrintHeader ( std::ostream &  os) const

Print head of the trace (e.g., for post-processing)

Parameters
osreference to output stream
